Performance Expectations:

HS-LS2-4. Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.

• Science & Engineering Practices

  Developing and Using Models - Develop a model to describe phenomena.

• Disciplinary Core Ideas

  LS2.B: Cycle of Matter and Energy Transfer in Ecosystems - Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.

• Crosscutting Concepts

  Energy and Matter - The transfer of energy can be tracked as energy flows through a system.
